How to fix SQL Index missing Statistics

02 January,2011 by Tom Collins

SQL Index Statistics missing - How can I view a list of indices and the last time the statistics were updated?

The STATS_DATE resturns the date the statistics for the specific index were last updated - the 2 arguments are table_id and index_id.The STAS_DATE could also be used in WHERE clause

The statblob column - is the Statistics binary large object(BLOB). Therefore the DATALENGTH (si.statblob) returns the number of bytes in for that column

 Use this DBA script to identify the last time statistics were updated

 

SELECT LastTimeUpdated = STATS_DATE(si.id, si.indid)

,TableName = object_name(si.id)

,Name = RTRIM(si.name)

,Size = DATALENGTH (si.statblob)


FROM sysindexes si WITH (nolock)

WHERE OBJECTPROPERTY(si.id, N'IsUserTable') = 1


order by LastTimeUpdated, tablename
